External witness

Who Emperor Valentinian I was

The blunt Pannonian officer who — the historians loved the story — had struck a pagan priest's lustral water from his sleeve as a tribune under Julian, and lost his commission for it; proclaimed emperor three years later, he gave the West a decade of hard frontiers and deliberate religious latitude, 'standing between the faiths,' Ammianus says, and troubling no man for his worship. He let the church elect Ambrose and let the temples stand; he died mid-shout, of a stroke, negotiating with barbarian envoys. Typed external per the emperor rule.
